APPARATUS FOR CASTING.

SPECIFICATION forming part of Letters Patent No. 511,265, dated December19, 1893.

Application filed August- 28, 1892. Serial No. 244,211. (No model.)

To (035 whom may concern:

Be it known that I, JOHN H. Oonunmson, of St. Louis, Missouri, have madea new and useful Improvement in Casting Apparatus, of which thefollowing is a full, clear, and exact description.

Theimprovement relates mainly, but not exclusively, to apparatus used inthe production of stereotypes, and more particularly to that classthereof in which the type is formed from an engraved plate, and itconsists mainly in the provision whereby the principal parts of theapparatus can be readily manipulated and variously adjusted and combinedto euable and facilitate the carrying out of the casting-operation, allsubstantially as is heremafter set forth and claimed, aided by theannexed drawings, making part of this specification, in which-- Figure 1is an edge elevation of the lower plate of the improved apparatus; Fig.2 the inner face elevation of the same; Fig. 3 a view representingeither the lower or the upper plate of the apparatus resting, with itsinner face turned thereto, upon any heating surface as preparatory tothe casting-operat1on Fig. 4 an edge elevation of the lower plate havingthe bar, which constitutes the inner or lower end of the mold during thecasting operation, attached, and the plate beng supported, by means ofits handle, in an inclined position; Figs. 5 and 6 views of the end-barshown in Fig. i;- Fig. 7 an edge elevation of the apparatus, the neargage-bar broken away; Fig. 8 an elevation of'thelower plate of theapparatus, with the plate, which, when engraved forms the matrix of thetype, the gage-bars, and the end-bar in position thereon; Fig. 9 a sideview of one of the gagebars; Fig. 10 an edge view of the apparatusclamped and ready for the casting operation; Flg. 11 a top view of thesame.

The same letters of reference denote the same parts.

The leading features of the apparatus, in its most desirable form, are,what may be termed, the lower plate A, the upper plate B, two gage-barsO, O, and an end bar D, together with suitable means, such as the clampsE, for binding the mentioned parts so eurely together. The plates A andB in width and height are sufficient to constitute the sides of theapparatus, their inner faces are smooth, and they are substantiallysimilar saving in respect to the connection with the end-bar hereinaftermore fully explained. The leading feature however of said plates is thehandles a, b, with which they are respectively provided. They serve notonly as a means by which the plates can be readily manipulated, eithersingly or jointly, and as a part or parts detached from the remainder ofthe apparatus, or by which the apparatus as a whole can be handled andshifted, but also as auxiliary supports for their respective plates whendetached from the apparatus, or from each other and arranged with theinner face thereof upturned, or for the entire apparatus during thecasting operation, and at other times. To these ends the handle projectsfrom the back of the plate, and preferably from the center thereof,substantially as shown, and its uses are fairly indicated in the variouspositions of the plates and apparatus shown in the drawings, andtheywill be more fully hereinafter described in connection with theoperationof the apparatus. The inner face of the plates need not be flatthroughout its length, but, at the upper end thereof, the plates may bebeveled, substantially as shown at a, b, thereby to provide, when theplates are united in the apparatus, a larger inletfor admitting themetal to be cast. A sufficient inlet however is obtained when only thebottom plate is beveled, and it is not essential that either plate shallbe beveled. The end-bar D, which forms the bottom of the apparatus, ispreferably detachable from the other parts of the apparatus, and thepreferable mode of supporting it in position in the apparatus is asindicated in Fig. 4:; pins, d, (1, project from the end bar, at one sidethereof, which enter perforations a o in the lower plate A. The end-barserves not only to properly space the upper and lower plates apart, butalso as a means by which the upper plate can be readily adjusted andheld longitudinally with reference to the lower plate, the end-bar, forthis last named purpose, having a shoulder d,against which the lower endb of the upper plate abuts when that plate isin position. The shoulder,

d, may be integral with the end-bar, but I prefer to make it in the formof a separate piece, such as the strip shown, and to attach it to theend -bar, to project therefrom as shown, say by means of the screws (1The end-bar also preferably has the offset (1 The gage-bars O, O, are ofthe ordinary shape, be g of suitable length and thickness, substantiallyas shown, to constitute the edge walls of the apparatus. They also eachmay have an olfset c, at the lower inner corner of the bar, and anextension c',at the lowerend of the bar, substantially as shown.

The operation of the apparatus is as follows: It is well understood acasting box should be suitably heated previous to the casting in orderthat the metal when cast shall be kept from chilling prematurely. Thisis quite desirably provided for by means of the plates and otherpartsbeing constructed as described. Each plate, by reason of itsdescribed shape, can be arranged upon,

. in, or against any suitable heating agent, and by means of its handle,the plate can be easily managed. Said heating agent may be any surface,part, or place, adapted to be heated, or having heat, and suited forreceiving and heating the plate. One such surface is indicated at F Fig.3. After the plates, as well as the other parts, are thus properlyheated they are assembled, together with the engraving plate G, orwhatever is to form the matrix of the type, as follows: The lower plateis upturned and supported by its handle, substantially as is indicatedin Fig. 4;

the end-bar, by dropping its pins into the hole in the lower plate isplaced in position upon the lower plate; the engraving plate, suitablyengraved (the engraving not shown) is then placed in position, its loweredge coming beneath or entering the ofiset, CF, in the end-bar, and theback of the engraving plate resting upon the inner face of the lowerplate; the gage bars are then placed in position, by arranging them uponthe inner face of the lower plate, with their extensions 0', o, in theoffset (i in the end-bar, and with the side edges of the engraving platein their respect ive ofisets, c, c, all as indicated substantially inFig. 8; that is the gage-bars are suitably spaced apart from each otherto suit the width of the engraving plate; the mold is now completed byapplying the upper plate B, to the parts already described, and in doingthis the lower end of the upper plate bears againstthe shoulder upon theend bar and the inner face of the upperplate comes against the endbarand the gage-bars, and, although in some instances, as when the weightof the parts of the apparatus is snfficient to hold them prop-.

erly together, any auxiliary binding device or means may be omitted,means such as the clamps, E, are usually applied to bind the two platesA and B, and the interposed gagebars, end-bar, and engraving plate,tightly together, and sufficient to prevent the escape of metal duringthe casting operation at the joints between the parts of the mold. Themode of applying the clamps is indicated in Figs. 10 and 11. The clampsshown are of a familiar type and hence do not require furtherdescription, saving that they may be utilized not only for clamping themold but also as a means for supporting the apparatus at this or thatinclination, and if desired, at a different inclination from that atwhich it is held by means of one of the plate handles.

In Fig. 7 the apparatusis shown supported at a suitable angle forcasting, by allowing the handle, a, of the lower plate A, to bear uponthe supporting surface H.

In Fig. 10 thelowerclamp,or clamps (when clamps are applied at bothcorners of the lower end of the apparatus), are brought into use as asubstitute for the plate handle, substantially as shown. The clamp isarranged well down toward the lower end of the apparatus, and theprojecting end, e, of the bar, of the clamp by coming in contact withthe surface H, serves to hold the apparatus in a more upright positionthan that of Fig. 7, a position sometimes desirable in order to increasethe pressure exerted by the fluid metal within the mold. This mode ofupholding the apparatus can be resorted to irrespective of the handlesupon the plates.

I claim 1. The combination, in acasting apparatus, of the lower plate A,recessed at a the shouldered end bar D, recessed at C1 and having pinsd, the gage bars, the upper plate and the clamps, said lower and upperplates respectively beveled at a and b, as and for the purposes setforth.

2. The combination in a casting apparatus of the lower recessed plate,the upper plate, the end bar shouldered and offset and having pins d andthe gage bars between the plates, each of said plates having handles andboth of said plates held together by a clamp, sub stantially asdescribed.

WVitness my hand this 21st day of July, 1892.
